But I still don't think renaming is_core_symbol() to is_kept_symbol()
is necessary.

And this series needs to backport to stable branches, no renaming can
reduce the difficulty.

This series prevents compiler generated local and mapping symbols
from leaking into /proc/kallsyms for loaded modules. This ensures
tracing tools like bpftrace can resolve accurate kernel stacks on
architectures like LoongArch.

Based on the v2 discussion, the changes are now refactored into a
clean three-patch series to eliminate code duplication and clarify
naming.
